Cobalt Twist Drill Bits for Metal, Steel, Cast Iron

From the brand MECCION, we offer a comprehensive range of home improvement and tools, including power tool accessories, hand tools, and home improvement solutions. In this product description, we'll provide you with essential tips and highlight the key features of our professional-grade drill bits.

Attention Tips: 1. When drilling, it's crucial to control the RPM to ensure optimal performance. 2. Avoid hitting the drill bit, as this can lead to breakage. 3. Ensure the drill bit is properly secured to prevent breakage due to vibration. 4. If the chip removal becomes abnormal, stop drilling immediately and resume only after addressing the issue. 5. During prolonged drilling, use oil for cooling to extend the drill bit's service life. 6. Drill bits are consumable items, and they may become dull over time. However, they can be resharpened and continue to be used.
